Students identify a chemical weathering example, name the landform formed by river sediment at an ocean, and identify the erosion agent that carved the Grand Canyon. Part B has five fill-in-the-blank problems about abrasion by wind, how chemical weathering differs from physical weathering, and the shape glaciers carve.
Identifying the erosion agent responsible for a specific landform requires students to connect process characteristics to observable landscape features.

Weathering and Erosion
Part A: Multiple Choice
Circle the best answer for each question.
1. Which is an example of chemical weathering?
A) Ice splitting a rock apart
B) Tree roots cracking a sidewalk
C) Acid rain dissolving limestone
D) Wind blowing sand against a cliff
2. What landform is created when a river deposits sediment as it enters the ocean?
A) canyon
B) delta
C) moraine
D) sand dune
3. Which erosion agent carved the Grand Canyon over millions of years?
A) glaciers
B) wind
C) flowing water
D) gravity alone
4. Why does freezing water crack rocks?
A) Water dissolves the minerals inside
B) Water expands when it freezes and pushes the rock apart
C) Frozen water is heavier than the rock
D) Ice makes the rock softer
Part B: Fill in the Blank
Write the correct answer on each line.
1. The process in which wind wears away rock by blowing sand against it is called abrasion.
2. Chemical weathering changes a rock's chemical makeup, while physical weathering does not.
3. A glacier carves a valley into a U shape as it moves.
4. Farmers plant cover crops to slow erosion of topsoil by rain.
5. Stalactites in caves form when dissolved limestone is deposited by dripping water.
